Brief Summary
This study is designed to study DNA sequencings for mutations in a research genetic test panel of genes (which contains all 32 known and/or published genes associated with PCD). The study aims to show that about 70% of PCD patients have biallelic mutations in one of these genes. This project will enroll patients who have already had a clinical evaluation, and have clinical features consistent with PCD.

Outcome Measures
Primary Outcomes (1)
Confirm PCD diagnosis in patients using a panel of 32 genes
The primary objective is to perform research genetic (Ampliseq panel) testing in patients who are known or suspected to have PCD, based on previous research or future clinical and lab characterization by certified clinical research sites. We will define the prevalence of biallelic PCD-causing mutations in patients who fulfill criteria of very high likelihood of PCD, as well as prevalence in other patients with some features of PCD. We anticipate successful completion of this objective will provide the foundation for development of clinically available genetic test panels, particularly as additional PCD genes are identified.
Up to 5 years
Secondary Outcomes (1)
Identify patients with PCD who do not have a biallelic PCD-causing mutation
Up to 5 years
Eligibility Criteria
Study participants should have 2 or more clinical features of PCD.
You may qualify if:
- Any patient who has ≥ 2 clinical features (+/- lab) characteristic of PCD, including:
- Neonatal respiratory distress after term (or near-term) birth
- and/or laterality defect ( situs inversus or heterotaxy)
- and/or daily wet cough before 6 months of age
- and/or middle ear disease
- and/or chronic nasal congestion before 6 months of age
- and/or bronchiectasis
- and/or male infertility due to sperm tail dysfunction
- and/or low nasal nitric oxide levels (\<77 nanoliters/minute)
- and/or defective ciliary ultrastructure
You may not qualify if:
- Known diagnosis of cystic fibrosis with classic clinical presentation and elevated sweat chloride levels and/or two known disease-causing Cystic Fibrosis transmembrane conductance regulator (CFTR) mutations, or documented primary or acquired immunodeficiency.
- Known explanation for bronchiectasis (and other clinical features), such as α1-antitrypsin deficiency (ZZ or ZS), inflammatory bowel disease or rheumatoid arthritis.
- Any patient who is unwilling or unable to provide consent or to comply with the testing required in this protocol
- A participant should not be in the study if they have not had a standard clinical evaluation to address other potential causes of chronic oto-sino- pulmonary disease.
